Abstract The science objectives of the LISA mission have been defined under implicit assumption a 4-years continuous data stream. Based on performance Pathfinder, it is now expected that will duty cycle $$\approx 0.75$$ <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:mrow> <mml:mo>≈</mml:mo> <mml:mn>0.75</mml:mn> </mml:mrow> </mml:math> , which would reduce effective span usable to 3 years. This paper reports results study by Science Group, was charged with assessing additional return increasing lifetime. We explore various observational scenarios assess impact duration main mission. find investigations most affected concern search for seed black holes at cosmic dawn, as well stellar-origin and their formation channels via multi-band multi-messenger observations. conclude an extension 6 years operations recommended.
